switch grass

Switch grass (Panicum virgatum 'Heavy Metal') requires moderate to frequent watering, depending on the seasonal climate. In hot or dry conditions, water weekly or even more frequently. In cooler or more humid months, water every other week. When watering, it's important to drench the roots thoroughly and allow the soil to fully dry out between waterings. Never allow the plant to sit in overly wet soil, as this can lead to root rot. As a general guideline, water around 2 to 3 inches deep, working the water towards the root zone. Finally, avoid overhead watering which can lead to disease, and instead opt for water at the soil level.

Switch grass (Panicum virgatum 'Heavy Metal') should receive at least 6 hours of direct sunlight each day. Morning sun is ideal as it will help the plant to remain lush and healthy. In general, switch grass performs best in full sun, meaning a minimum of 8 hours of sunlight each day, with at least 6 hours being direct sun.

Switch grass (Panicum virgatum 'Heavy Metal') should be pruned once a year in late winter, just before the new growth begins. Pruning should be done to remove dead foliage and create a more compact, attractive form. Take care to remove only unsightly or dead foliage; do not cut back into healthy green foliage. A light pruning is all that is necessary, removing less than 1-third of the top growth. Pruning too severely can slow down the plant's growth and reduce flowering.
